Chronograph stopwatch option isn't working

[Carolchloe]

I have my Blaze set to chronograph and when I push in the right lower button to quickly change to stopwatch it doesn’t change.

A warm welcome to the Community @Carolchloe.

Have you tried to restart your Blaze? If you haven't, I recommend restarting it by doing the following:

1. Press and hold the back (left) and bottom buttons until you see the Fitbit logo on the screen. This should take less than 10 seconds.
2. Let go of the buttons.

If the issue is directly with the button, you may be able to remove dust or dirt by gently using a toothpick around the button. If this does not improve the button performance, you can try to clear debris using canned air. Hold the tracker at arm's length and spray once to loosen any dirt or dust that may have accumulated around the button.

I hope this helps, let me know the outcome.
